DETACHABLE BUTTON.

SPECIFICATION forming part of Lettersratent No. 758,602, datedAprn 26,1904. Application nea March 19, 190s. Renewed nach 22, 190A. .serian/.1.199,428. No model' To a/ZZ whom it may concern;

Be it known that I, ALEXANDER HARRISON BROWNLEY, a subject of the Kingof Great Britain, and a resident.y of Onehunga, New

While my invention admits of general use, it 1s of peculiar value tosoldiers and sailors for use in connection with their uniforms.

I will describe a detachable button embodying my inventionand thenpointout the novel features -in the appended claims'. i

Reference is to behad to the accompanying drawings, forming a part ofthisspecification, lin which similar characters of reference'indicatecorresponding parts in all the figures. Figure 1 is a sectional sideelevation on the line 1 1 inFig. 2 of a detachable button embodying myinvention. Fig. 2 is an inverted plan or bottom view of the button.Figi?) is a sectional side elevation on the line 3 3 in Eig.

4; and Fig. 4 is an inverted plan somewhat similar to Fig. y2, butshowing the disks in a ,different relative position.

rIhe button-head 1 is provided with an eye 2 in the ,usual'mannen disk 3is provided with a bearing 4, in which is journaled a hasp A or swingingmember 5, provided with a pivotal bearing 42 The haspis provided with ahead 6 and aneck 7. The disk 3 is provided with a slot 8 of suitableconformity to admit the head 6. Another disk 9, somewhat larger than thedisk 3, is provided with a milled edge 10 and with a slot consisting ofa wide portion 11 and a narrower portion 14, the slot having a generalarc shape. The eyes 2 and the hasp 5 constitute the respective membersof a two-part fastener.

A pin 12, provided with a head 18, secures the two disks together, whilepermitting of more or less relative movement between them. The disk 9 isprovided with another arc-shaped slot 15, through which a curved tongue16, i-ntegral with the disk 3, passes. The disk 9' is provided with asmall hole 17, and the disk 3 is provided with a, raised annular bead18, preferably made by stamping. The bead 18 is free to engage the hole17 when the two disks are in therelative position indicated in Fig. 2.When, however, the two disks'are moved relatively to each other-as, forinstance, when the milled head 10 is turned-the two disks springslightly asunder, so that the bead 18 is free to glide from the hole 17and tobind slightly against the disk 9, as indicated more particularlyin Fig. 4. e It will be observed that the head 6 and curved tongue 1 6,passing through. the slots 14 15, constitute .a guide mechanism formaintaining thevdisks in aV predetermined relation. i

My invention is used as follows: The hasp 5 being opened, as indicatedin Fig. 3, the eye 2 of the'button-'head 1 is inserted, andthe hasp ismoved into the position indicated in Eig. 1,' Vthe head 6.and neck 7passing through the slots 8 and 11. When this occurs, the disks areinthe position indicated in Eig. 4.. The milled edge l0 now being graspedby the iingers is turned radially, so as to occupy the position'indicated in Eigf2, whereupon the bead 18 snaps into the hole 1.7 thussecuring the two 'disks together tolerably firm. The

'head 6 is nowin one end lof the slot 14, asindicated, so that the hasp5 cannot be moved. To take off the button, the milled head 10 is rotatedin the usual, direction until the parts assume the position indicated inFig. 4, and

the hasp 5 being swung into the position indicated in Fig. V2 the eye 2is then unhooked. `Having thus described my invention, I claim as newand desire to secure by Letters Patent- 1. A detachable button,comprising a button-head provided with one member of a twopart fastener,a disk provided with another member of said fastener, saidlast-mentioned member being free to swing relatively to said disk forthe purpose of engaging and disengaging said irst-mentioned fasteningmember,

a .second disk provided with a slot for engag? ing said swinging member,and means for connecting said disks together so as to permit relativemovements between the same.

2. A detachable button, comprising a button-head provided with onemember of a twopart fastener, a disk provided with the other IOO memberof said fastener, said last-mentioned member being free to swingrelatively to said disk for the purpose of engaging and disengaging saidfirst-mentioned fastening member, a second disk provided with a slot forengaging said swinging member` means for connecting said disks togetherso as to permit relative movements between the same, and guide mechanismfor maintaining said disks in a predetermined relation notwithstandingsaid movements.

3. A detachable button, comprising a button-head provided with onemember of a twopart fastener, a disk provided with the other member ofsaid fastener, said last-mentioned' member being free to swingrelatively to said disk for the purpose of engaging and disengaging saidfi rst-mentioned fastening member, a second disk provided with a slotfor engaging said swinging member, means for connecting said diskstogether so as to permit relative movements between the same, and alocking device for normally maintaining said disks in a predeterminedrelative position.

4. A detachable button, comprising a button-head provided with onemember of a twopart fastener, a disk provided with the other member ofsaid fastener, said last-mentioned member being free to swing relativelyto said disk for the purpose of engaging and disengaging saidfirst-mentioned fastening member, a second disk provided with a slot forengaging said swinging member, means for connecting said disks togetherso as to permit relative movements between the same, guide mechanism formaintaining said disks in a predetermined relation notwithstanding saidmove-V ments, and a locking device for normally maintaining said disksin a predetermined relative position.

5. A detachable button, comprising a button-head provided with an eye,adisk provided with a hasp pivotally mounted thereon for the purpose ofdetachably engaging said eye, and also provided with a slot for engagingsaid hasp, a second disk journaled upon said first-mentioned disk andprovided with an areshaped slot for temporarily securing said hasp whensaid disks are moved into certain positions relatively to each other,and a fastening device for normally securing said disks together in oneof said predetermined relative positions.

6. A detachable button, comprising a button-head provided with an eye,adisk provided with a slot, a hasp pivotally mounted upon said disk andprovided with a head and neck capable of passing through said slot, anda member revolubly connected with said disk and provided with aslothaving wide and narrow portions, said wide portion being free to admitsaid head and said narrow portion being too narrow to admit the head.

7. A detachable button, comprising a button-head provided with an eye, adisk provided with a head, a hasp pivotally mounted upon said disk andprovided with a head and neck capable of passing through said slot, amember revolubly connected with said disk and provided with a slot,having wide and narrow portions, said wide portion beingfree to admitsaid head and said narrow portion being too narrow to admit the head,and a fastening device for normally securing said disks together in apredetermined relative position.

8: A detachable button, comprising a button-head provided with an eye, adisk provided with a slot, a hasp pivotally mounted upon said disk andprovided with a head and neck capable of passing through said slot, arevoluble member connected with said disk and provided with a slothaving wide and narrow portions, said wide portion being free to admitsaid head and said narrow portion being too narrow to admit the' head, afastening device for normally securing said disks together in apredetermined relative position, said revoluble member being providedwith a milled edge to facilitate its movements relatively to said disk,and guiding mechanism for maintaining said disk and said revolublemember in a predetermined working relation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
